From Field to Fashion: The GOTS quality assurance system is based on on-site inspection and certification of the entire textile supply chain (processing and trade). Certification is performed by independent, approved 3rd party Certification Bodies, which is a requirement of an ISO 14024 Type 1 environmental labelling programme. Operators from post-harvest handling up to garment making, as well as wholesalers (including exporters and importers), have to undergo an on-site annual inspection cycle and must hold a valid certification in order for the final products to be labelled as GOTS certified.
